Subject: [PATCH v4 0/2] drivers: make early_platform code SuperH-specific
Date: Thu, 03 Oct 2019 09:29:11 +0000 [thread overview]
Message-ID: <20191003092913.10731-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
Some time ago I started a discussion about the need for a proper early device
probing mechanism[1]. One that would be based on real platform drivers and
support both platform data and device tree.
While we're far from reaching any consensus on the implementation, Arnd
suggested that I start off by moving the SuperH-specific early platform
drivers implementation to arch/sh[2].
This series is the first attempt at making way for a new, less hacky
implementation.
The first patch moves all the early_platform code to arch/sh.
The second patch prefixes all early_platform symbols with 'sh_'.

v1 -> v2:
- certain drivers are compiled for arm/mach-shmobile too - we need to
add ifdefs for CONFIG_SUPERH around early_platform calls
v2 -> v3:
- added a stub for is_early_platform_device() which always returns false
on non-SuperH architectures
v3 -> v4:
- rebased on top of v5.4-rc1
- removed patches that are already upstream from the series

drivers: move the early platform device support to arch/sh
sh: add the sh_ prefix to early platform symbols
